Types of a Lightning Arrester
choice of lightning arrester depends upon the following factors: Voltage Current Reliability Space available for installation Types of lightning arresters. Rod Gap Arrester Sphere Gap Arrester Horn Gap Arrester Multiple-Gap Arrester Impulse Protective Gap Arrester Electrolytic Arrester Expulsion Type Lightning Arrester Valve Type Lightning Arresters Thyrite Lightning Arrester Auto valve Arrester Oxide Film Arrester Metal Oxide Lightning Arrester Rod Gap Arrester It is one of the simplest types of Lightning Arresters . In the before-mentioned type, there is a gap between the end of the two rods. These two rods get connected to the earth and the line directly. The gap gets filled with air. When there is a higher voltage on the line, the air ionizes, producing a spark. In this fashion, the fault current passes to the earth. The process is explicated above in the snippet. Hence, the equipment is saved from potential damage. Sphere Gap Arrester In such types of lightning arresters, an ...
